No, I have not keeping up a build thread and I am build a Farfie inspiration Genesis V2100 with the custom extended arm waiting for my cromotor coming next week. I would post new build thread when it complete.

I still riding same old Tidalforce ebike with 9c motor. Anyways, Have you ever ride dbaker's cromotor ebike yet?

this evening we were going on a family bike ride to picnic by the kenwood cherry blossoms. but the GT was failing. odd power surges here and there. and i misplaced the trailerbike hitch to pull son. so i got home with an hour to try to fix up the dh comp. i whipped the motor back together and hooked up the sensorless controller:'

30 min to go, i tossed it on the bike, spun fine. tightened everything up. then horrible rubbing. snowchyld was right: metal on metal was a screw head hitting the caliper. i had tried to get away w/o a washer inside the dropout adapter, and when i did a final axle nut tighten, i must have pushed the calipers just enough to rub the motor! that explains that.

i think a hall is down too, but having a rear brake will make up for going sensorless.

so i added a washer, put the bike back together. but not in time for the picnic!

my wife took off hauling two kids and i had to drive. or did i? i had another 10 min, and realized there'd be no place to park, so whacked on the controller, put the rest of the bike together, tested it in the alley, and then took off with son in front of, his feet on my feet.

a couple miles on the bike path without pedaling once.

so yeah, emil, if we get a break in the weather this weekend, let's race.

you'll have the start advantage w/ sensored controller, and i'm inquiring from lyen how to get my speed switch working cause there's no connector for it and it's stuck on 2, so you may have a chance... you may have to pedal tho.

I`m glad you are lucky considering your ~700wh pack i doubt you will ever want 2nd to use them in series However you still can ask your friend dbaker if he have one spare in case you decide to leave one at work and the second one at home. That was the way it worked for me.

anyway to make it 41.5v you will need to short the pin D1 to the pin A3 and to make it power on the pin B3 should be connected to A3after it powered on, you can use voltmeter to adjust the pot on the top of the case to the exact voltage you want.

I believe the following picture will explain where to solder AC-in(P1-P2) and DC out(P4=positive and P5=negative) wires and do not forget to use at least 12awg wires for DC output - I tried 14awg initially and those were hot to touch after 2-3 minutes of use, So I replaced mine to 12awg.

andrey, you make it too easy for the other 10! thanks, i will need this soon!

that is: IF i get ONE ebike running. both are DOWN right now. i'm so mad, frustrated and embarrassed.

GT i drive:- halls & phase wires test beautifully on ebike tester (get one if you don't have one)- tried TWO identical working controllers, same problems - wheel spins but with no power whatsoever, and (slowly) at different speeds using speed switch!- i've never seen anything like this. - 83V everywhere - perhaps the magura throttle line? maybe the inline resistor broke. i'll test a diff controller. that may explain random pulsing i had last week. - or, maybe a rat crawled in the motor after charlie loosened the sidecover? i can test with another motor... ok, that's a plan of action at least. less mad now.

DH COMP

enjoying the island?? i wished we could have raced - that way this controller could have lived for longer than TWO rides!

- a hall is dead - or more likely shorted somewhere on the axle - that white plastic woven sheath is shredded near the bearing, so it was surprising it ran on friday- but on Saturday, i poked the programming connector with multimeter probes and probably ruined the chip - - that's just a suspicion. i was trying to find a 5V source for my temp sensor, and since there wan't a speed switch connector. one connector gave 5V between the black and other wires, but later lyen reminded me that was the programming connector when i asked him how to solder to the board to add a speed switch connector. might as well build up the bike right and do the proper upgrades. so i popped the controller, added the speed switch, but could not get the bike to run after that! even w/ speed switch disconnected. and something smelled a bit funny.

i may have blown the chip. i'm going to try to program it next, to see if it's alive.

if not, i'll be pretty pissed, as this destructive streak is getting out of hand.

i hopped on my road bike to commute this morning, but the gears are broken.

What a maniac, that trials stuff blows my mind how they can just leap up in the air and down over things like that.Some of that stuff was shot about half an hour from my house!

And yeah that youtube stabilization looks weird! Could be a cool effect if you wanted it in select places though. Good to see you back riding. Hopefully the bad luck is behind you!You clear, smudge free gopro videos make me sad
